# Wyvern
A centralized storage management system for Minecraft. Basically Dragon, rewritten for sanity and improved networking/error handling.
Requires Plethora Peripherals by SquidDev (as that's what allows item transfer by wired network).

## Goals
1. Support big, multi-user setups.
2. Work sanely and reliably even in bizarre edge cases.
3. Be pretty fast.
4. Function conveniently for end users.
5. Be relatively easy to connect other systems to.
6. Allow complex automation.

## Setup
`installer.lua` is recommended for running everything.
Get it with `wget https://osmarks.tk/git/osmarks/wyvern/raw/branch/master/installer.lua`.

Run `installer install` to download everything. It will open an editor for the config file, allowing setup of a node.
When prompted for a program to run on startup, say `client` to configure it as a client or `backend-chests` to run the chest backend.

If you just want to update Wyvern, run `installer update`.

### Networking & Hardware

```
Chests ───────┐
   │          │
Server ─── Buffer
   │          │
   └────┬─────┘
        │
        ├────────── Processing (not implemented yet)
        │
        │
   ┌────┴──┬───────┐
Client  Client  Client
```
* **Chests** is a set of chests and/or shulker boxes, connected via networking cables and modems, to the **Server** and **Buffer**. Cookie jars are not compatible.
* **Buffer** is a dropper with a wired connection on the chests' side and clients' side.
* **Server** is a computer running `backend-chests`. Other backends may eventually become available. It must be connected to the chests, clients, and both sides of the buffers.
* **Client** is a crafty turtle running `client`. It must be connected to the server and external side of the buffers.
* **Processing** will be used for autocrafting systems. It is not yet implemented.

### Configuration
Configuration is stored in `wyvern_config.tbl` in lua table syntax as used by `textutils.(un)serialise`.

#### Client
`network_name` must contain the network name (thing displayed when modem beside it is rightclicked) of the client turtle.

#### Server
`buffer_internal` must contain the network name of the buffer on the chest side.
`buffer_external` must contain the network name of the buffer on the client side.
`modem_internal` can contain the network name of the server on the chest side. This is only required if your network contains chests on the client side which are connected.

## Warnings
* Inserting/extracting items manually into/out of chests will result in the index being desynchronised with the actual items. To correct the index, run `reindex` in the CLI client.
* If you try and extract items when the storage server is still starting up, it may fail, as not all chests will have been indexed yet.
* There are currently small problems with extracting certain quantities of items from storage. Yes, it should probably be by stack.
* Yes, I am kind of using git wrong, but editing networked CC programs sanely is *very hard*. Tell me if you find a better solution.

## Usage
Once configured, the chest backend can just be plugged in and ignored, unless it explodes.
For help using the client, run `help` or `h`.

## Coming Soon(ish) (maybe)
* Audit log on server - see when items were moved.
* Overlay glasses/introspection module client.
* Autocrafting (just a port from Dragon's).
* Autosmelting (basically autocrafting).
